No full textMusica, prisão e gênero: Uma leitura de Rita Segato para pensar decolonidade nas práticas musicais
No full textThroughout this work, we aim to reconsider Rita Segato’s contribution to decolonial turn in order to show what it involves when thinking about decolonization in music practices, particularly, in correctional institutions. As a turning point, we offer to rebuild the concepts based on Segato’s original thoughts intertwining Aníbal Quijano’s coloniality of power perspective together with a gender perspective. This provides the necessary elements to analyze gender/race in prison and to address the political and theoretical proposals of the author in terms of historical project of bonds and politics in a feminine key (Segato, 2018a, 2018b, 2019). Then, taking advantage of the categories and definitions Segato provides we analyze two musical experiences which took part in women’s prison no. 8 of the Penitentiary System of the province of Buenos Aires, showing the scope of the author\u27s developments when naming the experience —in this case, the musical experience in close connection with prison as an institution— as well as when identifying its politicity. Finally, we point out that Segato is not stranger to the music field and that her conceptualizations, as alternatives to the Eurocentric categorical grid, allow us to think about music practices in a situated mode and in a decolonial key. El siguiente trabajo propone retomar el aporte de Rita Segato al interior del giro decolonial para mostrar la contribución que dicho aporte implica a la hora de pensar la decolonialidad en las prácticas musicales y, en particular, al interior de la institución carcelaria. Como punto de partida, ofreceremos una reconstrucción conceptual que nos permita advertir el original aporte que Segato ofrece al entrecruzar la perspectiva de la colonialidad del poder de Aníbal Quijano con cuestiones de género. Esto nos brindará los elementos necesarios para pensar la cárcel en la intersección raza/género, y para abordar las propuestas teórico#políticas de la autora en torno al proyecto histórico de los vínculos y la política en clave femenina (Segato, 2018a, 2018b, 2019). Luego, pondremos en juego las categorías y definiciones que ofrece Segato para analizar dos experiencias musicales llevadas a cabo en la cárcel de mujeres n.° 8 del Sistema Penitenciario Bonaerense en el año 2017, mostrando los alcances de los desarrollos de la autora a la hora de nombrar la experiencia —en este caso, la experiencia musical, en estrecha vinculación con la cárcel— e identificar la politicidad de estas prácticas. Por último, señalaremos que Segato no es ajena al ámbito musical, y que sus conceptualizaciones, en tanto alternativas a la grilla categorial eurocéntrica (Segato, 2013), nos permiten pensar las prácticas musicales de un modo situado y en clave decolonial.O seguinte trabalho propõe retomar a contribuição de Rita Segato dentro da Virada decolonial, para mostrar a contribuição que essa contribuição implica ao pensar a decolonialidade nas práticas musicais, particularmente dentro da instituição prisional.

No full textCoproduction in mental health organizations: how to make it work
No full textContext
Against the increasing incidence of mental health diseases worldwide, recovery is emerging as an effective method, focused on the strict collaboration of professionals with patients, their relatives, and the society at large, in order to design, manage and evaluate the patients’ personal care pathways. However, despite recovery and co-produced approaches proved to facilitate the patients’ rehabilitation and wellbeing, evidence on how they can be successfully implemented in mental health organizations still lacks. This paper aims to assess potential enablers and barriers for the application of coproduction approaches in health care organizations, through a literature review and an empirical analysis.
Methods
A systematic literature review has been carried out to identify enablers and barriers that encourage or limit the adoption of coproduction in healthcare organizations. 647 papers were identified through the keyword search and 84 were selected as coherent within the research’s aim. 28 different models and methodological approaches emerged from the search. However, they tended to be very general and no model explained how to implement coproduction in mental health organizations; thus, an empirical analysis was completed to gather evidence in support of this unexplored domain.
Specifically, we selected four mental health organizations in Northern Italy, which are trying to adopt coproduction approaches in different organizational settings. Overall, 11 patients, 5 caregivers and 10 professionals were interviewed about their personal experience on coproduction and the perceived enablers and barriers. The interviews lasted 14 hours and 12 minutes, they were recorded, transcribed and validated by the interviewees.
Results
The literature research showed that the presence of a widespread network in support of coproduction (professionals, caregivers, policy makers, etc) that is trained accordingly facilitates the implementation of coproduction, as well as the use of shared medical plans, co-designed among professionals, patients and relatives. These enablers were confirmed in the cases, despite relatives are not always keen to be involved.
About the barriers, both the literature and the practice point at the absence of solid methods to assess the return of investment for coproduction: policy makers hardly know what coproduction is and the current organizational and financial systems are not aligned with it (i.e. fee for service vs. personal budget of care). Yet, the literature stresses that professionals are seldom willing to collaborate equally with the patients, while the cases show the opposite. However, practitioners perform coproduction practices on top of their required activities, without being rewarded for it.
Discussion
Informed by the literature, the cases provide indications about priorities for future research in the field of patients’ involvement in mental health care.
First, there is a need to generate methodologies to assess the outcomes of these approaches. All the interviewees agreed that coproduction is time-consuming and hard, but worth it: this evidence should be translated into measurable items and assessed. The assessment and widespread communication of positive results may determine a twofold advantage in our view: first, it shows policymakers and health organizations’ managers that coproduction is effective; second, it increases the social acceptance of people affected by mental diseases patients.
Second, new ways to improve knowledge and commitment of professionals, relatives and patients towards coproduction are needed. For example, psychiatrist and psychologists’ training paths could include specific courses on it, while patients and families could be reached by targeted communication campaigns in schools, job places, or public locations

No full textImplementing co-production in mental health organizations
No full textPurpose The purpose of this paper is to study four cases of the adoption of co-production and compare them according to the type of user involvement, contextual factors and the organizational structure. Design/methodology/approach In total, 30 interviews were conducted in four mental health organizations which are implementing co-production in the North of Italy. Interviews were conducted with clinicians, nurses, patients and family members. The data collected was triangulated with further sources and official documents of organizations. The results have been compared by means of a validated international framework (IAP2) regarding the contextual factors and the level of co-production adopted. Findings The adoption of co-production in the four cases differs by the activities implemented and how organizations involve informal actors. It seems to be influenced by the contextual factors specific to each organization: power, professionals' opinions and leadership. Organizations whose practitioners and leaders are willing to distribute their power and value informal actors' opinions seem to facilitate the systematic involvement of users. Overall, the results highlight the importance of considering contextual factors when evaluating and describing co-production activities. Originality/value This paper contributes to describing how mental health organizations are implementing co-production. It examines the influence of contextual factors on the type of co-production adopted
Tecniche di taratura di stereocamere per missioni planetarie
No full textOptical instruments for space missions work in hostile environment, it’s thus necessary to accurately study the effects of ambient parameters variations on the equipment.
In particular, optical instruments are very sensitive to ambient conditions, especially temperature. This variable can cause dilatation and misalignment of the optical elements, and can also lead to rise of dangerous stresses in the optics. Their displacements degrade the quality of the sampled images.
In this work the optics and mountings of a stereo-camera for the BepiColombo mission are modelled and processed by a thermo-mechanical FEM analysis, reproducing expected operative conditions. The output is elaborated into a MATLAB optimisation code, based on non-linear least square algorithm to determine the equation of the best fitting nth polynomial or spherical surfaces of the deformed lenses and mirrors; model accuracy is 10-8 m.
The obtained mathematical surface representations are then directly imported into ZEMAX for sequential raytrace analysis. The results are spot diagrams, chief ray coordinates on the detector, MTF curves and Diffraction Encircled Energy variations due to simulated thermal loads.
This helps also to design and compare different optical housing systems for a feasible solution. Different types of lenses and prisms constraints have been designed and analysed. The results show the preferable use of kinematic constraints instead of glue to correctly operate the instrument to maintaine in focus in orbit around Mercury considering an operative temperature between -20°C and +30°C.Gli strumenti ottici che vengono utilizzati nelle missioni spaziali risentono delle variazione delle condizioni ambientali, per questo è necessario studiare l’effetto di queste ultime sull’equipaggiamento.
In particolare gli strumenti ottici sono molto sensibili alle variazioni di temperatura, perché questa grandezza può causare la deformazione e il disalinneamento delle ottiche, inoltre può comportare l’insorgere di tensioni rilevanti che possono provocare la loro rottura.
In questa tesi sono state effettuate delle analisi termo-elastiche utilizzando un software ad elementi finite (Nastran) riproducendo le condizioni operative in cui si troverà la stereocamera coinvolta nella missione BepiColombo. I risultati delle analisi sono stati elaborati in MATLAB per determinare le equazioni matematiche delle superfici degli elementi ottici deformati utilizzando un’ottimizzazione non lineare ai minimi quadrati, e considerando equazioni polinomiali, sferiche e planari.
Le superfici matematiche sono state importate in un software raytrace (ZEMAX) per poter verificare la performance ottica dello strumento. I risultati mostrano come le variazioni di temperatura influenzino gli Spot Diagrams, la Diffraction Ensquare Energy e le curve MTF.
Per migliorare la risposta del telescopio ai carichi termici sono stati ideati dei vincoli cinematici, il loro utilizzo compromette molto meno la performance della stereocamera rispetto a vincoli rigidi per le ottiche.
È stata valutata l’influenza delle variazioni dei parametri ottici (focale, spostamento del centro ottico, spostamento degli Spot Diagrams sul piano immagine e distorsioni) sulla ricostruzione della profondità della superficie di Mercurio utilizzando la propagazione dell’incertezza secondo le metodologie GUM e Monte Carlo.
Infine è stato ideato unsetup strumentale per determinare gli spostamenti e le rotazioni di alcuni elementi ottici della sterocamera in camera di vuoto riproducendo le condizioni operative dello strumento
Variations of the lipid levels in morbid obese patients operated with the LAP-BAND Adjustable Gastric Banding System: the effects of different levels of weight loss
No full textBACKGROUND: A moderate weight loss is known to improve the lipid levels in simple obesity. The extent of weight loss needed to achieve a clinically meaningful effect on lipid abnormalities in morbid obesity is little understood. We analyzed the effects of different levels of body weight loss on the lipid levels of morbidly obese patients operated with the LAP-BAND System.
METHODS: 225 morbidly obese patients (172 F and 53 M) in which a complete lipid profile has been collected both before and 12-18 months after surgery were studied. The changes of the lipid profile were analyzed according to different levels of percent weight loss (%WL: 30%).
RESULTS: Mean weight loss was 30.7+/-15.2 kg, corresponding to a 23.1+/-9.7% reduction of body weight. A large variability in the weight loss was observed. A significant difference in the change of the lipid parameters between the group with 30%WL) and the group with 10-20%WL, the only exception being the percent change in triglycerides levels, i.e. higher in the group with %WL >30 (-33.6+/-31.5% vs -21.9+/-25.4%; p<0.05).
CONCLUSION: A moderate weight loss of 10-20% of initial body weight produced the maximal effects on the lipid levels in morbid obesity
